Answer:</h3>
6 cm, 8 cm, 12 cm
<h3>
Step-by-step explanation:</h3>
The perimeter of the reference triangle is ...
... (15 +20 +30) cm = 65 cm
Then the similar triangle has a scale factor of ...
... (26 cm)/(65 cm) = 2/5
Multiplying the side lengths of the reference triangle by 2/5, we get ...
... {15 cm, 20 cm, 30 cm) × 2/5 = {6 cm, 8 cm, 12 cm}
These are the side lengths of the smaller similar triangle. (Check: their sum is 26 cm.)
Step-by-step explanation:
Step 1: Multiply the numerators from each fraction by each other (the numbers on top). The result is the numerator of the answer.
Step 2: Multiply the denominators of each fraction by each other (the numbers on the bottom). ...
Step 3: Simplify or reduce the answer.
it's really simple if you still need help tell me

Answer:
○
Step-by-step explanation:
All you are doing is plugging numbers into each answer choise to determine the equation and constant of variation. When you do, you will arrive at this answer. You could also apply mental mathematics to determine whether or not these chart displays a scale factour of 4, which they do.
